Trinity of God
The word “trinity” is not found in Scripture. It is a word used by Christians to express the doctrine of the unity of God as consisting of three distinct Persons. This word is derived from the Greek word trias, first used by Theophilus (A.D. 168-183), or from the Latin trinitas, first used by Tertullian (A.D. 220), to express this doctrine.
This is the wondrous reality of God:
The Holy Spirit is also a distinct divine Person.
Dr. John MacArthur comments,
God is one, yet He is three. I haven’t got the faintest idea how to explain that divine mystery to everyone’s complete satisfaction, but my own inability to articulate it in a way that answers everyone’s questions doesn’t diminish my faith in God or my conviction that He exists as One in three persons.
And that’s okay. The doctrine of the Trinity stands as a perpetual reminder we cannot comprehend everything God has revealed about Himself. All that I can write about God, when compared to the totality of His attributes, is like one grain of sand compared to every beach, every mountain, and every planet in the universe. In order to comprehend God, we would need to be God’s intellectual equals, but He has no equals and doesn’t tolerate the impudent pretense of anyone who claims to understand things better than He does (Job 40:6–41:34).
Heretics over the centuries have tried to explain the Trinity in several ways. Sabellius said that at times God appears as the Holy Spirit, at other times as the Son, and other times as the Father—just one person, with three manifestations. But the Bible does not support that. God is not a quick–change artist. And as we have seen, at Jesus’s baptism all three persons of the Trinity were manifested at once. God is one, and yet He is three at the very same time. —Dr. John F.
